The continuity tester allows you to test & confirm the effectiveness of your grounding product. There's no need to purchase this with your initial grounding product (unless you'd l ike to see the science in action!), and NorthStar products are designed with the highest silver thread content to ensure long-lasting effectiveness, but if you've accidentally put your product in the dryer with heat or want to confirm effectiveness after 6-12 months of use, it can be a great tool. Here is a quick, easy video on how to use the tester! Show more
